Referring more indetail to the accompanying 55 drawings and parnoulanyaofmgures l1 warner@ is illustratedran airplane toy comprising a body portion or fuselage 10 carrying a plane or wing l1, `the rear `end of ythe fuselage 10 carryinga dependingv skid 12. The Wheeled landing gear'for the airplane toy includes a pair of resilient strap to irons, each having apair of legs 13 divergingat their upper ends and attached to the underside of the wing 11i-While the lower ends of theflegs 13 Adiverge to form a bearing 14`for the support .'ofan axle `lrthat carries a ground wheel 16 upon h5 Y each end thereof. Each leg 13 is curved transversely as shown at 13a in Figure 5 for strengthen'- ing the landing gear, but Without removing the 'resiliencythereo A propeller blade 17 is carried by the'forward 'end of the fuselage 10 while alhorizontallydis- 'posed helicopter propeller` blade 18 is located above the fuselage at la point intermediate the ends thereof.' The' driving means for the propeller'blades 17'and 18 includes a frame of `in verted U-shape as shown in Figure 3 that includes a crosshead 19 carrying depending side legs 20 'to beset into the-fuselage 1i) as shown in'Figure 1, the lower ends df lthe side legs 20bein`gjbi VfurcatedltoA provide spaced Ylugs 21 Yfor passage B0 through openings in the bottom wall of Athe'fuselage 210 vand thereafter bent at right angles'for locking the Vframe 4in position. `A shaft -22 is Journalied in 'the Siae legs Vzo ofthe frame with zthe ends thereof projecting outwardly of Atheside *5'5 legs, each provided with va hook 2'3. I Abevel gear V2'4 is keyed tothe shaft 22 adjacent oneend thereof-atthe inner side of one of the legs2'01an`d is in "meshing engagement with the bevel gear y25 keyedV to the'shaft 26 Vjournalled inthe cross 90 vhead '19 of the frameythe shaft 26 projecting `upwardly 1through the'wing `1l1 and having Ythe Vhelicopter 'propeller blade -18 fixed thereto.

The rotating means 'for the shaft 22 includes a pair of elastic tapes 129,

vone `of which is 'shownV in detail in Figure 4, as

-tape's 29'are 'respectively attached'to-a hookl no wardly positioned propeller blades 17 as well as the helicopter propeller blade 18 lthrough the medium of the meshing'gears 24 and 25. It isl possible to store sufiicient energy in the elastic tapes 29 to cause the airplane toy to fly through the air, shocks incident to landing being absorbed by the resilient legs 13 of the landing gear.

In the form of invention illustrated in Figures 6 to 8, the shaft 22a is journalled in the vside legs 20a of the inverted U-shaped frame, the heli-v copter propeller being eliminated and laterallyy positioned propeller blades *'33 are carried Vvby shafts 34 journalled in the wing 11a laterally of the fuselage 10a. The shaft 22a is rotated by the elastictape 29 attached to the Vhooks 23a, `the rear end of the rearwardly positioned elastic tape 29 being anchored v.at a ypoint adjacent the rear en d of the fuselage while the forward end of the forwardly positioned elastic tape29 is attached to the forwardly positioned propeller blade 17 a. The,

drive means for the laterally positionedpropeller blades 33 include a` pair of belts 35, both passing ,over the shaft 22a and respectively passing over theshaft 34 at their outer looped ends. The elastictapes 29 are placed under tension by reversely` rotating the forwardly positioned pro-l pellerblades 17a, power therein being imparted Vto the shaft 22a for the driving of the belt 35 forthe operation of thelaterally positioned propeller blades 33, the shaft 22a directly driving .through fthe medium ofthe elastic tapes,y the forwardly positioned propeller blades 17a,

n As diagrammatically illustrated in Figure 9, the fuselage 10b; carries a forwardly positioned propellerblade 17h and a pair of helicopter propeller blades 18a and 18h respectively, the propeller blade 18a being preferably operated by a'gear drive such as shown in detail in Figure 3, .while the propeller blade 181)` may have .the belt connection-With the'` shaft 26 that supportsY theY 'I `-helicopter-propeller blade 18a.
